* Example for Getting Started with nRF24L01+ radios.
|
||||
*
|
||||
* This is an example of how to use the RF24 class. Write this sketch to two
|
||||
* different nodes. Put one of the nodes into 'transmit' mode by connecting
|
||||
* with the serial monitor and sending a 'T'. The ping node sends the current
|
||||
* time to the pong node, which responds by sending the value back. The ping
|
||||
* node can then see how long the whole cycle took.

* Example LED Remote
|

*
|

* This is an example of how to use the RF24 class to control a remote
|
||||
* bank of LED's using buttons on a remote control.
|
||||
*
|
||||
* On the 'remote', connect any number of buttons or switches from
|
||||
* an arduino pin to ground. Update 'button_pins' to reflect the
|
||||
* pins used.
|
||||
*
|
||||
* On the 'led' board, connect the same number of LED's from an
|
||||
* arduino pin to a resistor to ground. Update 'led_pins' to reflect
|
||||
* the pins used. Also connect a separate pin to ground and change
|
||||
* the 'role_pin'. This tells the sketch it's running on the LED board.
|
||||
*
|
||||
* Every time the buttons change on the remote, the entire state of
|
||||
* buttons is send to the led board, which displays the state.

* Example RF Radio Ping Pair which Sleeps between Sends

*
|

* This is an example of how to use the RF24 class to create a battery-

* efficient system. It is just like the pingpair.pde example, but the
|
||||
* ping node powers down the radio and sleeps the MCU after every

* ping/pong cycle.
|

*
|

* As with the pingpair.pde example, write this sketch to two different nodes,
|
||||
* connect the role_pin to ground on one. The ping node sends the current
|
||||
* time to the pong node, which responds by sending the value back. The ping
|
||||
* node can then see how long the whole cycle took.
